Data values with /summon?

Question

I wish to summon a wet sponge in front of me. I know:

/summon Item ~ ~ ~ {Item:{id:minecraft:sponge,Count:1}

But I don't know how to add wet sponge's data value (1) in that command.

There seems to be a lack of online information on this topic.

Answer 1

The item's data value is stored as the Damage tag:

/summon Item ~ ~ ~ {Item:{id:"minecraft:sponge",Count:1,Damage:1}}

The wiki has a list of all item NBT data here.

Answer 2

I believe the wet sponge is a different block, so it works with another name ID. Using minecraft:wet_sponge ought to work.
